s claims. (c1. 2 8) Our invention relates to Welders helmets.

In operations involving welding, and in similar operations, it is 'attimes important to proteot the faceand eyes. At times protection of theeyes only is required, while at other times it is necessary that theentire face be'protected. In welding, the change of conditions fromthose requiring completeiace protection to those requiring eyeprotection only may occur frequently and at short intervals and forcomparatively brief periods. As one hand of the operator is generallyoccupied in holding a torch or other implement, it is desirable thatmeans `be provided whereby the change from completelfaceshielding to eyeshielding only, and vice versa, may be accomplished quickly andconveniently by the use of one hand only,

` One of the objects of our invention is to provide a welders helmet'inwhich thisk change may be accomplished easily and quickly by the use oione hand only. y y

A further object of our invention is to provide a welders helmet havinga face mask and an auxiliary eye shield in which the movementy of theface mask from shielding position to non- Vshielding position willautomatically cause the eye shield to move from nonshielding to eyeshielding position.

A further object of our invention is to provide animprovedadjustable-eye shield for. use in a welders mask.

Further objects and advantages of the invention will be apparent fromthe description and claims.

In the drawing, in which an embodiment of our invention is shown, y

Figure 1 is a side viewof a welders helmet, part elevational and partsectional, the section being substantially on the line I-,I of Fig..2; y

Fig. 2 is a vertical sectional view, substantially on the line 2-2 ofFig. 1;

Fig. 3 is a detail plan viewv'on a smaller scale showingthe mounting forthe eye shield; and

Fig. 4 is a vertical sectional view substantially on the line 4 4 ofFig. 3.

The construction shown in the drawing comprises a'headbandY or harnessI, a face mask 2 pivotally carried thereby and movable from faceshielding position A to a position B above the face, an eye shield 3pivotally vcarried by said band and movable from eye shielding positionC to a position D above the eyes, and transmission between said mask 2and eye shield 3 whereby, when the harness is in place on the head,-motion of the mask from shielding position A to nonshielding position Babove Lthe facewill move thel eye shield from nonshielding 'position ,Dto shielding position C, and whereby motion of the mask fromnon-shielding position B to shielding position A will'move the eyeshield from shielding position C to nonshielding position D above theeyes. The mask may, in general, be of the construction disclosed in thepatent to yAnderson No. 2,270,028. i

The maskz is pivotally mounted on the headband I by means of a pair ofpivot bolts or screws 4, nonrotatably secured to the mask and rotatablein bearing brackets orstraps 5 secured to opposite sides of the headband.by means of fasteners 5. Each pivot bolt 4 is rigidlysecuredl to theYmask by means of .a `pair of nuts "I, one on each side of the sheetmaterial used in the mask, the outer nutbeing tightened up to grip andclamp the sheet material of the mask between the Itwo nuts.v

In order to provide a frictional engagement for holding the mask andheadband in adjusted position,v acoil compression spring 8 is providedacting between a pair of washers 9, one of which bears against the nut land the other of which bears against the mounting `strap 0r bracket 5.

The eyeshield 3 is pivotally secured to the headband I by means of apair of rivets III extending through apair of pivoted L-shaped rock armsI I on` which the eye shieldr3 is mounted.

The construction by means of which lifting of the mask causes loweringof the eye shield, and vice versa, comprises a pair of brackets or armsI3 rigidily secured to the pivot bolts 4, respectively, each providedwith a crank pin or follower I4 which operates in a slot I5 on the L-shaped rock arm which carries the eye shield 3. In considering theeiiect of raising and lowering the'mask on the movement .of the eyeshield, it should be noted Vthat the pivot bolts 4 are fixed withrespect `to the mask 2 and that the crank arms I3 and crank pins I4 rockwith themask 2 and pivot bolts 4. From this, it follows that the rockingmovement of the crank pins I4 which slide in the slots I5 will cause a=rocking action of the L-shaped rock .arms II Vi/vhichfcarry the eyeshield in such a way thatV when the mask 2 is raised the eye shield 3will be lowered, and that when the mask 2 is lowered the eye shield 3will be raised. The crank arms I I and I3, crank pins I4, and slots I5are so proportioned and designed that when the mask is pulled down sothat the chin strap or rest I6 rests on the chin, the eye shield 3 willbe raised above the eyes and away from the sight openings I'I in themask the desired position, leaving the other hand free.A

The pivot pins 4 which carry the crank arms I3 may be rmly secured inany desired position of rotary adjustment with Arespect to the mask 2 byloosening the nuts 1, adjusting theY pins 4 rotarily with respect to themask and again tightening up the nuts. This enables the crank pin I4 tobe set in any position desired with respect to the mask 2 to change therange ofv movement of the eye shield 3 with respect to the range ofmovement of the mask 2.

AThe eye shield comprises a semicircular band or strapl of flexiblematerial, riveted at I9 to the L-shaped "rock arms II, and a'somewhatcrescent shaped shield of flexible transparent material detachablysecured to thesemicircular strap.

`In order to adjust the vshield for different wearers or for differentsituations, means are provided for securing the transparent shield 2D indifferent positions of adjustment on the semicircular band. For thispurpose, as shown in Figs. 3 and 4, `one or both ends of the shield are'provided with snap fastener pockets or eyes 2l, similar to glovefasteners, for engagement with cooperating snap fastener buttons 22 onthe semicircular band I8. The central portion of the transparent shieldis provided with a plurality of eyes or depressions 23, any one of whichmay bebrought into engagement with a cooperating button 24 secured tothe central portion of the band I8. To change the adjustment, one of theeyes 2l is disengaged, the eye 23 on the transparent shield isdisengaged from the button 24 on the strap and a different pocket 23 isbrought intoregistration and engaged with the button on vthe strap, andthe glove fastener eye 2| is again snapped into engagement with thecooperating button 22 on the semicircular strap. The lower centralportion of the eye shield 3 may be cut away, as indicated at 25 in Fig.2, and may have a raised portion 26, as shown in Fig. 1, to provideclearance for the nose of the wearer when the shield is brought downinto shielding position.

As described above, the crank pin I4 may be set vin any desired positionwith respect to the mask 2 to change the range of movement of the eyeshield 3 with respect to the range of move- `ment of the mask 2. Theindividual wearer can adjust the helmet by loosening up the nuts 1,

placing the helmet on the head in the most comfortableposition, raisingthe mask 2 over the head and drawing down the eye shield 3 in frontofthe eyes, and then tightening up the nuts 1 on both sides of the mask,thus automatically locating the maskpand eye shield in their properrelative position. If, thereafter, any minor adjustments are needed,this can be accomplished rbyadjusting the veye shield 3 by means of the4 button 24 and the series of eyes 23 on the eye shield.

Further modications will be apparent to those skilled in the art and itis desired, therefore, that the invention be limited only by the scopeof the appended claims. l

Having thus described our invention, what we claim and desire to secureby Letters Patent is:
